I have a strange pressure in my right upper chest area?

It started this morning and it feels like a long thin tightening from my colar bone to about 3 or 4 inches down my chest. But only when i cough or laugh other than that I can barley feel it. What is it and what should I do about it. Thanks

you could've pulled a muscle especially if you've been doing push ups or plank exercises, it doesnt sound serious just take ibuprofen if it hurts enough, you could put a hot compress on it, it will allow the blood flow to circulate better in that area
